To all vjliwfnf. t may concern lic it known that 1, Henner Soncini, a

Francisco, in the county of San Francisco and State of California, have invented nevv and useful Improvements in Adjustable linpact-ufltoinizers, ci ivhich the fn-)llovving` is a specification.

The object ot the present invention 1s to provide, in a device for' atemizing liquids mechanically, that is, Without the aid of steam or compresse air, improved nieans,

quantity dischar ed, will at the saine time and independent y' of the variations in the discharge, effect desirable variations of the shape or angle of the spray)` 4 .In the' accompanying' drawing", Figure 1 is' a longitudinal sectional View or a mechanical sprayer equippedl with my; improvement; Fig. 2 is an end View ol the jetdivider shdvvnin Fig. 1; Fig. 3 is a broken longitudinal section of a modified form of a modified form of Tet divider shovvn in Fig. 3. Referring to the drawing, 1 indicates a housing, having formed thereon a' suitable transverse flange 2, said housing being at ternally threaded nozzle 3 which has a dis= charge orifice 4. At the other end the housing is internally threaded to receive an eX- ternally threaded sleeve 5, having a projecting portion 8 by which it may be screwed into the end of said housing, the latter havu ing a shoulder 6 against Which rests a Harige 'of a sleeve 7 forming lWith said sleeve 5 a stalling box. At said latter end, the house". 11g is also externally threaded, to receive thereon a hand wheel 9, connected by a spider 10 With a hub 11, which is secured by a set screw 12 to a pipe 13 passing through said sleeves 5 and 7. ln the end of said pipe 13 Within the housing' is secured a tubular regulating valve 14, formed at its outer end with a flange 80, which Vcan slide Within a jet Wardly extending flange 16, with which Athe Valve 14 slides in contact. To take up the lost motion of the regulating valve, a helical spring 17 is interposed between the jet di vider and 'a disk 18 resting against the pipe 18.

Within the regulating valve 14 can slide the stern 19 of a conical valve 20 adapted to seat in the discharge orifice e in the noz- 'zlef '.lhe rear portion of said valve stem passes through astuiing box 31 secured on the end of the pipe 13, and its rear end is secured to a hand Wheel 22 screwed into the outer end of the stalling box 2l. By this Ineens the vulve 2O can be adjusted longitudinally'. number of channels' 23, three being lhere shown, are formed in the -cylindrical outer surface of the jet divider, parallel to the axis thereof, and opening into channels 24Cl extending obliquely inward, as.

vider, as shown at 28, and terminating in Y inwardly directed obliquely-extending chan-l nels' 29. The liquid to be atomized is forced under great pressure through the channels 24.- or 29 of the jet divider, and is divided into small streams or jets which inipinge either upon the inside-of the nozzle 3, or Wholly or partly upon the tapering valve 20, so that the liquid, When escaping through lthe discharge orice of the nozzle, is atom` ized and assumes the forni of inist. The longitudinal movement, above indicated, of the regulating valve 14 is employed to vary the size of the discharge ends of said channels. By moving longitudinally the valve 20, to vary the extent of its surface upon which the jets impinge, the shape which the vapor assumes' when discharged from the nozzle is varied. This is an iinpor'tant requirement in many industrial lines. Notably in the burning of liquid fuel under steam boilers it is very iinportant to have, not only means of regulating speedily the quantities of fuel to be discharged, but also means for varying the shape oi the llame to suit the furnace setting.

1. In avnozzle having a housing and a discharge orilice, a central stein having' a tapering valve Within the housing, cao-axial means Within the housing having channels for the liquid and discharging inwardly Within the' cliargevoriice, a central stem having a tapering valve within the housing, co-axial means within the housing having channels for the liquid and discharging inwardly within the housing adjacent to said tapering valve and Aatl-right angles thereto, a tubular valve around said stem, movable longitudinally to regulate the size of the discharge ends of said channels, means operable from the exterior of the vhousing for so moving said tubular valve, vand means independently operable from the exterior of the nozzle to move said tapering valve relatively to said discharge ends. v

3. A fluid fuel burner comprising a casing having a fuel inlet passage, a tubular member secured to `and entered in the casing, a cap for the casing having a fuel discharge orifice, said cap and tubular member forming a vortex chamber therebetween said member having a tangential 4inlet port to ksaid chamber, means for simultaneously governing the size of said chamber and port, and means for controlling said discharge orifice.

4. A fiuid fuel burner having a fuel supply passage, a fuel outlet opening, a vortex chamber communicating with said opening, a tangential port through which fuel is introduced to the vortex chamber, a chamber. contracting member, and an independent` valve controlling the fuel outlet opening.

v5. A fluid fuel burner having a fuel supply passage, a fuel outlet opening, a vortex chamber communicating with said o ening, a tangential port through whichy fue is introduced to the vortex chamber, a chamber contracting and port controlling member, and .an independent valve controlling the fuel outlet opening.

6. Awfiuid fuel burner comprising a casing having a fuel inlet passage, anV elongated tubular member entered in the casing and disposed to form a passage for fluid between the casing and the said member, a oap for the casing having a fuel discharge opening, said cap and member forming a vortex chamber therebetween, a port in said member communicating with said p-assage and entering said chamber tangentially, means for varying the volume of the vortex chamber, and independent means for controlling the fuel discharge opening. In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
